There are some problems in traditional polymer physics experiment teaching
such as outdated knowledge
scattered knowledge points and independent experiments. The experiments are oriented to the problem that transparency and heat resistance of polymer are difficult to be combined
and the hot material biodegradable poly(lactic acid) is used as a research object to link polymer processing
crystallization behavior
physical properties and characterization methods through experimental design. This experimental course can promote students’ integration of multidisciplinary related knowledge
and at the same time cultivate their independent and independent problem-solving ability
which is very suitable for the experimental teaching of polymer majors.
